IMPROVEMENT IN CARPENTERS GAGES.

Specification forming part of Letters Patent No. 115,368, dated May 30,1871.

lo` all persoas to whom these presents may come:

` Be it known that I, DANIEL WEBSTER SIM- MONS, of Lynn, of the countyof Essex and l State 'of Massachusetts, have invented a new and usefulImprovement in the Joiners Gage;

and do hereby declare the same to be fully dei scribed in the followingspecilication and represented in the accompanying drawi g, of

4 i and make such knife in the shape of a wheel or disk, and to revolveon a pivot extending `from the stock,`the edge fof the periphery of 4thewheel or disk-knife being ground sharp and beveled entirely from theouter side of the knife. i c

` In the'drawing, A denotes the stock or bar, and B ythe rotarydisk-knife `or scorer, the pivot or journal of the latter being shown ata. The gage-slide is exhibited at C as applied to i y the stock in theusual way, and provided with `a clamp-screw, D. v

The aforesaid new arrangement of the cutter and its form Iand `mode ofoperation (it revolving on its pivot while in use) renders theimplementmore durable and4 advantageous than the common gage, asprovided with the stationary cutter.

The cutter,by revolving, maintains its edge i sharp longer, and is notliable to become heated while in use so as to draw its temper, as it isconstantly presenting a fresh portion of its edge to the wood whiledrawn along such.

I am aware of the gage shown and described in the United States PatentNo. 12,861, granted to F. P. Hart,`and make no claim to anything,construction, or arrangement of parts thereof. An important differencebetween my gage and 4that of Hart isV that the rotary cutter of my gagehas thebevel on its edge sloping toward the end of the shank, and noprojection extending beyond the outer face of the cutter,V suchimprovement enabling my gage to be used in a rebate, when that of Hartcould not be so employed, owing to its journal-screw and nuts beingextended beyond the outer face of its cutter, and the edge of the cutterbeing beveled in a direction contrary to what is the case with that ofthe rotary cutter of my gage.

I claim, therefore, as my invention- An improvement in the joiners gageas made with the stock A, the adjustable slide O, and

rotary conic-frustum-cutter B, the said cutter, t

as arranged, withits lesser Vbase against or at the end of the stock,and with its pivot applied so as not to project beyond the outer face orlarger base of the cutter, all being as described and represented. Y
